Actually the 416 does have 10x5 bearings .. but the older ones dont have 11x5 , they are 9x5. I knew the newer ones were bigger. The 05 i have is an older one but the castor blocks and steering blocks are diferent than my 416. I'd like to know if the indentation is in the top of the castor blicks like my 416 and not like my 05. And since the axels are different lengths and as well as the drive shafts I think I will just wait till i can get the arms sepperate. but thanks 4 the info.
